In order to estimate energy expended and metabolic heat produced during Border Patrol BP training or operations, 14 male BP personnel were studied over the course of a day. Energy expenditures in kilocalories kcal was determined for each activity by individual. Total energy expenditure for the work day -7 hours was then established and metabolic heat production estimated assuming mechanical 20 for human movement. It was found that BP personnel expended approximately 1750 plus or minus 540 kcal during their work day which would result in an estimated 24-hour daily energy expenditure of 3150 kcal. An average of 240 plus or minus 60 W of heat was produced over the entire work day 1 kcalhr 1.163 W. Peak metabolic heat production for activities lasting 30 minutes or longer was an estimated 360 plus or minus 204 W.
